BUILT-IN PROM VERSIONS
(1) PROM mode
The built-in PROM version has a PROM mode in addition to a nor-
mal operation mode. The PROM mode is used to write to and read
from the built-in PROM.
In the PROM mode, the programming adapter can be used with a
general-purpose PROM programmer to write to or read from the
built-in PROM as if it were M5M27C256K. Programming adapters
are listed in Table 26.Contact addresses at the end of this sheet for
the appropriate PROM programmer.
• Writing and reading of built-in PROM
Programming voltage is 12.5 V. Write the program in the PROM
of the built-in PROM version as shown in Figure 51.
(2) Notes on handling
ŒA high-voltage is used for writing. Take care that overvoltage is
not applied. Take care especially at turning on the power.
For the One Time PROM version shipped in blank, Mitsubishi
Electric corp. does not perform PROM writing test and screening
in the assembly process and following processes. In order to im-
prove reliability after writing, performing writing and test
according to the flow shown in Figure 52 before using is recom-
mended (Products shipped in blank: PROM contents is not
written in factory when shipped).

Screening (Leave at 150 °C for 40 hours) (Note)
Verify test with PROM programmer
Function test in target device
Note: Since the screening temperature is higher
than storage temperature, never expose the
microcomputer to 150 °C exceeding 100
hours.
